Be it known that l. llewwr l5. lilNFEUYI, a citizen of the lnitcclSlater refilling! at Davenp rt, in the county of Scott :nnl h'tntc ofIon :1. have invented vermin n w will use ful lmproveinenu in Wheels. ofwhich the following is :1 spiwil'irntiom ri' l'erenm'e living l'ltltltherein to the accompanying: drawing i This invention relates to metalwheels in which the spokm are rigidly fastened to the huh by h nuts. orshouhlem on the spokes formed usually h v upsetting or riveting the mimeor by like operation it is the ommon practice in the manufacture ofwheels of this type to provide the huh with hollow spoke sse t re eivethe spoke howls. the Stlltl bosses projecting outwardly from the spokeand forming local recesses or rarities in the huh rommunienting, withthe axial vhninlwr therein. Wheels of this comtrnrtion are frequentlyprovided with two li llli'h oi spokes; and for certain usesanti-friction hearings are mounted in the hub rhznnheix For the bestresults the two hearings shouhl he spaced apart axially from each othera corn side able distance in order to properly (listrihute the loud onthe axle; :ltlli to serurc the greatest strength and bracing :puilitieeof the spokes it. is (lmdmhle also to spare the two ranks axially nconsiderable tllht lllf'il from each other. This chwirnhhilisponitionand relation of the hearings nnil Fill). of spokes necessitates that oneat least i the hearings be hunted in axial :ilineincnt with one of theranks of spokes, but this IllSI'NlSltion of the parts is impracticablebecause of the presence of the hollow spoke bosses and the consequentlocal cavities in the Wall of the huh the presence of such cavitiesrentien ing the hub unsuitable and unfit; at this point to afford asufficiently solid and efl'ectiv'e support for the bearing ring of theantifriction bearing.

It is the aim of the present invention to overcome this objection and,to provide :1 construction wherein the two ranks of spokes may bedisposed the proper distance apart, and the two bearings also properlyspaced and at the same time provide e firm and effective sup ort for thebearing ring; and with this on in view I propose to dispense with thehollow spoke bosses and Specification of Letters Patent,

Referring to the drawings: 1 represents nv wheel eons-:ioti 1;;- of ahuh 2 having the usual rhanil-er 9*, a rim 3, and two series or ranks ofspokes an outer rank 4 and an inner rank 5. which two ranks are fastenedat their outer ends to the rim, and at, their inner ends to the lllilkand spaced from cswh other in an axial clirection at their point ofconnection with the. hill The inner ends of the spokes extend throughredial holes in the hill; anal are ecnrcel thereto in the pres-- entinstan e eimnhlers ti on the spokes hearing nymph; the outer filtifii ofthe hub, and hemls i on. ll" nner end of the spokes, whirl] litllilfiproject into the hub chamber and which are preferably flattened usclearly shown in Fig. L Qitunted within the hub chamber are twoantifriction hearings an outer hearing 8 and an inner hearing 9. Thesebearings comprise each an outer bearing ring 10, an inner bearing ring11. and a series of interposed rolling elements in the form of. bearingrollers 12, the inner hearing rings being mounted on an axle 13projecting axially within the hub chamber.

The bearing ring of the outer bearing 8 is seated against and given firmsupport by the flat spoke heads 7, thus disposing the bearing in radialalinemcnt with the spokes of this rank, and permitting the two ranks tobe spaced from each otherin an axial direction a suliicient distance tosecure the full and greatest strength and bracing qualities ofthespokes.

In the construction shown the inner hearing 9 is disposed inward of theinner rank of spokes, the outer bearing ring of said bearing beingseated against the inner wall of the hub chamber at a point inward ofthe inner spokes.

As a result of the two bearings the construction described, are soseparated from each other as to distribute the load on the axle underthe most favorable conditions for efiective operation; and the two ranksof spokes are likewise separated from each other a suflicient extent tosecure the best and most effective results.

hile in the foregoing description and accompanying illustration I havedisclosed my invention in the particular form which I Egefer to adoptand which in practice has en found to answer to a satisfactory deree theends to be attained, it will be anerstood that various changes may bemade in the details thereof without departing from the spirit of theinvention, provided that the operation of the' parts will besubstantially as indicated above, the essence of the invention residingin supporting the antifriction bearing by the inner proje ting ends ofthe spokes, so that the spokes and hearing may be disposed in alinementwith each other, and the bearing given a firm and solid support withinthe hub.

Having thus described my invention, what I claim is:

1. In a wheel, the combination of a hub provided with an internalchamber, spokes connected fixedly their inner ends exposed within thechamber. and an antifriction bearing siftilutcd. in the chamber andincluding an dxtcrhal bcaring ring seated against and supported by saidends of the spokes.

2. In a wheel, the combination of a hub having an internal chamber,spokes connected rigidly with thc'hub and provided with beads extendingin the chamber. and an antifricfiop bearing situated in the chamber andincluding a bearing seated against and supported by said spoke heads.

3. In a wheel, the xiol'nbination of a hub provided with an internalchamber, spokes connected fixedly with the hub and provided on theirinner ends with flat heads exposed within the chamber, and anantii'riction bearing situated withinthe chamber and including a bearingring seated against and supported by said flat spoke heads.

4. In a wheel, the combination of a hub provided with an internalchamber, spokes fixedly connected with the hub in two ranks spaced fromeach other in an axial direction, the inner ends of the spokes of onerank being provided with beads extending within the chamber. anantifriction bearing situated in said chamber in line with one of theranks of spokes and including a bearing ring bearing against andsupported by the heads on the spokes of said rank, and a scc ondantit'riction bearing situated in said chamber adjacent the other rankof spokes; whereby the two ranks of spokes and the bearings may beproperly spaced from each other.

In testimony whereof, I have afiixod my signature in presence of twowitnesses.
